A concise and efficient approach to synthesizing coumarin-fused pyrazolo[3,4-b]pyridine via silica sulfuric acid (SSA) catalyzed three-component domino reaction under microwave irradiation has been demonstrated. Participation of various alcohols in construction of coumarin derivatives has been described for the first time. Short reaction time, high yields, one-pot procedure, usage of eco-friendly catalyst
已经证明了在微波辐射下通过二氧化硅硫酸(SSA)催化的三组分多米诺反应合成香豆素稠合的吡唑并[3,4-b]吡啶的简洁有效的方法。首次描述了各种醇类参与香豆素衍生物的构建。该方法的主要特点是反应时间短、收率高、一锅法、使用环保催化剂和溶剂。
